About the calculator

The calculator aims to give car owners a gauge on the time(in hours) the battery will last based on the battery’s capacity and the average current that the car is consuming from it. Typically the larger the battery capacity is, the longer the operation time. With the inclusion of the power consumption of the vehicle, it will affect the discharge time of the battery. If you have any questions or feedback on the calculator, feel free to drop us an email here.

Units of measurement

List of Units of Measurements (UOM) used in for the Battery Discharge Time Calculator:

• Amp hours (Ah)
• milliAmp hour (mAh)
• Amps (A)
• milliAmp (mA)
• Hours

Formula

Discharge Time (Hours) = Battery Capacity(Ah/mAh)/Current Consume(A/mA)
